Abstract

Tehnologije raspodijeljenih registara, od kojih su najpoznatiji lanci klijetki, pojavljuju se 2009. godine kao rješenja za postizanje konsenzusa u bizantinskom okruženju. U ovom diplomskom radu objašnjena je funkcionalnost najpopularnijih javnih lanaca klijetki, čiji se razvoj može podijeliti prema njihovim funkcionalnostima. Bitcoin, kao prvi javni lanac klijetki koji rješava problem dvostruke potrošnje, ima glavnu funkcionalnost digitalnog novca, tj. bilježenje i prijenos vrijednosti. Ethereum, kao inovacija, uvodi pametne ugovore koji znatno proširuju funkcionalnost dotada prilično primitivnog Bitcoinovog skriptnog jezika. Trenutno se Ethereum suočava s problemom skalabilnosti, pa se prirodno javljaju rješenja za taj nedostatak bez narušavanja decentralizacije i sigurnosti mreže. Telegram Open Network je mreža koja uz sve funkcionalnosti Ethereuma uvodi trenutno usmjeravanje po hiperkocki te mehanizam vertikalnih popravki, čime poboljšava skalabilnost za više redova veličine. Pošto je područje lanaca klijetki te općenito raspodijeljenih registara popularno, i iz dana u dan se razvijaju nove decentralizirane platforme, mogućnost interoperabilnosti medu njima dobiva na važnosti.

Abstract (english)

Distributed ledger technologies, the most famous of which are blockchains, emerged in 2009. as consensus solutions in the byzantine environment. In this thesis, the functionality of the most popular public blockchains is explained. The development of blockchains can be divided according to their functionalities. Bitcoin as the first public blockchain to solve the problem of double spending has the main functionality of digital money, ie. recording and transferring value. Ethereum as an innovation introduces smart contracts which significantly expand the functionality of the hitherto rather primitive Bitcoin’s scripting language. Currently, Ethereum is facing a problem of scalability, however, remedies arise naturally, without decreases of decentralization and network security. One of them is Telegram Open Network, a network that, with all the functionality of Ethereum, introduces instant hypercube routing and ”self-healing” vertical blockchain mechanism, thus improving scalability by several orders of magnitude. Due to the popularity of the field of blockchains and generally distributed ledgers, new decentralized platforms develop on a daily basis, hence, the possibility of interoperability among them is gaining in importance.
